 Mediastinal vein at a little before two-thirds of the length of 

 the wing ; subcostal ending at about three-fourths of the length, 

 connected with the radial by a transverse veinlet at its tip ; radial 

 and cubital springing from a common petiole, which is less than 

 half their length, and which forms a right angle near its base; 

 radial forked near its base ; cubital forming near its base a very 

 obtuse angle, whence proceeds the first externo-medial ; the latter 

 is rectangular near its base and is forked towards its tip, and is 

 connected with the third externo-medial by two transverse vein- 

 lets ; the outer one of these forms a slight angle, whence proceeds 

 the second externo-medial vein; third externo-medial connected 

 with the subanal by a transverse veinlet, which joins the middle 

 of the hind side of the discal areolet.
